Big news here.

We are phasing in NEW locks!

We came to this decision after years of using a 7-pin tube lock:

After  extensive product research and consumer feedback, we have determined that from hereon, all Mail Boss mailboxes manufactured will incorporate a new 12-Wafer Disc Lock:

Why the change?

More Secure

  • Thousands more potential combinations
  • More difficult to pick
  • Hardened steel layers – more difficult to drill out

Ease of Use

  • No pressure required to turn key
  • Smaller surface area decreases likelihood of debris penetrating locking mechanism

As with any locking mechanism, we still recommend periodic maintenance with Tri-Flow as a preventative measure to keep your lock operating smoothly. However, we are hopeful that the new 12-wafer disc locks will offer our customers a superior locking mechanism with years of trouble-free operation.

One caveat:

The new locks will still include 3 keys. However, they will be more expensive to replace. You can buy replacement keys Replacement Flat Key, but they will cost about $15 each, as the labor for laser cutting these keys individually is significant.

Please be patient with us as we sell through existing inventory and update our product descriptions online to reflect the change.

As always, if you have any questions, please contact us at we will respond ASAP!
